[0042] Referring to FIGS. 11 and 12, the valve stem 6 includes a stem body 601 and a boss 602, wherein the diameter of the boss 602 is greater than that of the stem body 601; after the valve stem 6 is connected to a pressing cap 9, an upper end surface of the boss 602 is in contact with the pressing cap 9; the lower end surface of the boss 602 is provided with a limiting groove 603 which is annular and used for limiting an upper end of the resilient piece 7; a fixing groove 604 is provided on the inner wall of the upper part of the stem body 601; and after the stem body 601 is connected to the pressing cap 9, the valve stem 6 is fixed to the pressing cap 9 by matching the fixing groove 604 with the pressing cap 9; an inner protruding rib 605 is provided on the inner wall of the stem body 601, a valve needle 3 is inserted into the stem body 601, and the inner protruding rib 605 is inserted into the annular groove 304 to fix the valve needle 3 with the valve stem 6.

[0043] Referring to FIGS. 13 and 14, the resilient piece 7 is of a hollow cylindrical structure, an upper support portion 702 is provided at the upper end of the resilient piece 7 for being inserted into a limiting groove 603, a lower support portion 703 is provided at the lower end of the resilient piece 7 for being inserted into the upper support groove 503, the resilient piece 7 is limited by the connecting lid 5 and the valve stem 6, and when the valve stem 6 is driven to move upwards by pressing the pressing cap 9, the upper support portion 702 and the lower support portion 703 of the resilient piece 7 are supported and limited by the limiting groove 603 and the upper support groove 503; on one hand, the resilient piece 7 is prevented from being misaligned at the upper and lower ends to make the resilient piece 7 lose supporting resilient force; on the other hand, the air inside the resilient piece 7 of a hollow cylindrical structure is not easy to flow out, and the air pressure increases; the resilient piece 7 has a greater resilient force when used with the valve stem 6, and facilitates the ejection of the contents upon pressing; when the pressing cap 9 is released, the resilient piece 7 itself and the air pressure are used to facilitate the resetting of the resilient piece 7, and further facilitate the resetting of the pressing cap 9 and the contents entering the piston 4 and the bottom of the pump body 1 to form a cavity structure, which has a greater resilient force, has better sealing performance, and does not cause liquid leakage.

[0044] Furthermore, a protrusion 701 is provided in the middle of the resilient piece 7, the protrusion 701 is an arc surface, a first bevel 704 is provided at a connection between the protrusion 701 and the upper support portion 702, and the first bevel 704 is a conical surface; the diameter of the resilient piece 7 axially extending from the protrusion 701 to the upper support portion 702 gradually decreases; a second bevel 705 is provided at a connection between the protrusion 701 and the lower support portion 703, and the second bevel 705 is an inverted conical surface; the diameter of the resilient piece 7 axially extending from the protrusion 701 to the lower support portion 703 gradually decreases; when the pressing cap 9 is pressed downwards, the valve stem 6 moves downwards; the upper support portion 702 is pressed, the first bevel 704 presses the protrusion 701 downwards, and the protrusion 701 expands outwards, so as to realize the compression of the resilient piece 7; since the diameter of the resilient piece 7 located at the protrusion 701 is greater than the diameter of the first bevel 704 and the second bevel 705, the flexibility of the protrusion 701 is relatively greater, and the hardness of the first bevel 704 and the second bevel 705 relative to the protrusion 701 is greater; the protrusion 701 provided facilitates the resilient piece 7 to be compressed, and the first bevel 704 and the second bevel 705 provided facilitate the resilient piece 7 to reset from a compressed state, the pressing cap 9 is released, the resilient piece 7 is reset, the valve stem 6 is pushed to move upwards and reset, and the resilient piece 7 made of plastic replaces the spring made of metal, so as to facilitate the recycling of the perfume pump, and further achieve the requirements of environmental protection and energy saving.

[0045] Referring to FIGS. 15 and 16, a sleeve 1001 is provided inside the big ring 10, a support ring 1002 is provided inside the sleeve 1001 for supporting the connecting pressing cap 5, a clamping groove 1005 is provided on the inner wall of the sleeve 1001, the connecting pressing cap 5 is inserted into the sleeve 1001, a first outer flange 502 is embedded in the clamping groove 1005 to connect the connecting pressing cap 5 with the big ring 10, an annular groove 1003 is provided between the sleeve 1001 and the inner wall of the big ring 10 for limiting the horizontal direction of the pressing cap 9 to reduce the shaking generated when pressing the pressing cap 9, and an internal thread is provided at an opening of the lower end of the sleeve 1001 for connecting the bottle body.

[0046] In another embodiment, a bottle body is provided, an external thread is provided at the opening of the bottle body, and the bottle body is connected to an all-plastic perfume pump and a bottle body used therefor for storing perfume.

[0047] Working principles of the present invention: [0048] when a perfume pump is in use, a big ring 10 is connected to the bottle body, a spacer 11 is located at an opening of the bottle body to play a sealing function, a pressing cap 9 is pressed downwards to drive the valve stem 6 to move downwards to drive the valve needle 3 and the piston 4 to move downwards, the valve stem 6 and the connecting lid 5 pressing the resilient piece 7, the contents in the cavity structure formed by the piston 4 and the bottom of the pump body 1 are squeezed; at this time, the plastic bead 2 is subjected to a downward pressure to block the bottom of the pump body 1, the space in the cavity structure increases, the contents push the piston 4 upwards, the valve needle 3 continues moving downwards under the external pressure, and the space in the cavity structure gradually reduces to separate the sealing conical surface 402 from the sealing ring 305 and expose the liquid inlet 302; the contents in the cavity structure enter the liquid outlet 303 from the liquid inlet 302, then are sprayed out of the spray sheet 8 as a mist via the valve stem 6 and the pressing cap 9; after the bottom surface of the pressing cap 9 is in contact with the bottom surface of the annular groove 1003, the pressing cap 9 stops moving upwards to complete one-time spraying; [0049] the pressing cap 9 is released and the spring 7 elongates to push the valve stem 6 to move upwards to drive the valve needle 3 to move upwards, the space in the cavity structure gradually increases, and a negative pressure is generated in the cavity structure; the contents inside the bottle body move along the suction tube 12 under the action of atmospheric pressure and push the plastic bead 2 to enter the cavity structure; since the plastic bead 2 under the same volume is lighter than the glass bead, the plastic bead 2 can be separated from the bottom interface of the pump body 1 under a relatively small pressure of the contents, so as to achieve feeding; when the pressure inside the cavity structure and the pressure inside the bottle body are balanced, the sealing ring 305 of the valve needle 3 is attached to the sealing conical surface 402 of the piston 4, so that the contents do not flow back into the bottle body, at this time, the cavity structure is used for temporarily storing the contents to be sprayed next time.

[0050] It is to be understood that the described embodiments are only a few, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art and related fields without inventive effort should fall within the scope of the present invention. The structures, apparatuses, and methods of operation not specifically described or illustrated herein, if not specifically described or limited, may be practiced by conventional means in the art.
